The headlight above the windows is correct for many early SD70ACe locomotives and for Norfolk Southern ES44AC locomotives. The latest SD70s and most ES44s, however, have the headlight in the nose. So Lionel is not incorrect in terms of the placement of the lights for certain UP and BNSF engines--although their road numbers can be incorrect. The 2014 catalogue shows new BNSF, CSX, Canadian Pacific, UP, and other ES44 models using Norfolk Southern bodies with the upper lights, not nose lights as are actually on the real engines. Lionel could easily introduce "new" models with a mere change of the SD70 and ES44 cab plastic and change of painted road numbers. It would be inexpensive, accurate, and a temptation for those who have already purchased the original SD70 versions with the upper lights and want to add "new" SD70s and/or ES44s. It is a simple matter to alter the lights oneself, but reshaping and repainting the upper body can be challenging. The locomotives have a retail price of over $500. That is a lot of money to pay for an inaccurate version that Lionel could easily fix with a $2 piece of plastic.
I'm holding on to my pre-orders until I can find out for sure what Lionel will actually deliver. If they decide not to spend the little extra effort to make a more typical and more accurate model, I'll have to pin my hopes on the 2015 catalogue and wait another year.
